Enhanced Standoff Detection Capability for SNM Using High Purity Germanium Detector Based Instrumentation
ثبت نشده
چکیده
The difficulty of locating and identifying radiological sources over large areas is well known. The signal strength of a small-volume source diminishes according to the familiar “inverse square law” as the detector is moved away from the source. Ever-present fluctuating background levels exacerbate the problem when the source strength is weak compared to the background count rates from other sources and scattered radiation.

Energy linearity of high-purity germanium detectors in the region of the Ge K-absorption edge: experimental results
Non-linearities in the energy response of gas detectors in the regions of the absorption edges of the detection medium are well documented. Monte Carlo calculations show that the non-linearity results from differences in efficiencies for converting absorbed radiation into ionisation for different atomic sub-shells. Energy non-linearity in germanium-based solid-state detectors in the region of t...
متن کاملThe response of high-purity germanium detectors to X-rays with energy in the region of the Ge K-absorption edge.
The response of a high-purity germanium detector to X-rays in the 8-15-keV energy region has been investigated. The w-value and energy resolution dependencies on the X-ray energy have been studied. No abrupt variation of w is observed at the germanium K absorption-edge (11.104-keV). The detector energy resolution follows a characteristic linear dependence on Ex(-1/2) over the whole energy range...

متن کاملDigital Timing Algorithm for High Purity Germanium Detectors
The next generation of γ-ray detector arrays will be composed of large volume high purity germanium (HPGE) detectors that are electronically segmented. These detectors will be able to track γ-rays as they Compton scatter within the crystal and between adjacent crystals, eliminating the need for Compton suppression detectors and improving angular resolution. The new arrays will have much higher ...
